This self-coaching tip is really simple.
Brighten up your environment with some beautiful flowers and bring the outdoors in.
If flowers are not your thing, hang up a picture or display an ornament which inspires or relaxes you. I find that I can think better and I feel better when my home is tidy, and conversely mess stresses me out!
In NLP terms, the environment where you live is the simplest component you can change or improve in the Neuro-Logical Levels (Robert Dilts, 1990).
If you don't have much space, just dedicate one surface or wall to the place where you will create a little beauty in your home. Keep that space clutter-free and make sure it is where you can relax and gaze at it often. It will bring a little joy to your day.
